  1. In 1957, all 289CI Studebaker V8s used the 'dished' pistons....and 'normal' 289s were advertised to have an 8.3-1 compression ratio......However, the supercharged Golden Hawks advertised compression ratio was 7.5-1...I believe (not 100% sure) that all the '57 289's used the thicker composite head gaskets from the factory, hence the compression change would have to be in the combustion chamber.
  2. If these are '57-'58 Studebaker Golden Hawk heads, they should be OK, as Golden Hawk's of that vintage had less compression than the other period Stude V8's....Since pistons were all the same, (dished), the compression change had to be in the heads....Suggest you use thick (composite) head gaskets with this setup.
  3. Very interesting!.... and Avanti Gray is a fairly rare factory color!
